The object of my present invention is to so construct a torpedo of thetype here shown that the rail-engaging strap serves to lock and hold theflaps in position, and the flaps assist in holding the rail-engagingstrap. In the accompanying drawings, Figure 1 is a perspective viewof myimproved torpedo looking at the under side thereof. Fig. 2 is a crosssectional view of the torpedo.

showing it applied to a railroad rail. Fig. 3 is an inverted plan viewofthe torpedo. Fig. 4 is a perspective view showing the parts of thetorpedo in separated relation.

The torpedo case comprises a central portion 1 which is shaped to form acavity 2 to receive a tablet compound 3. This central portion 1 has anannular flange 4 and this annular flange 4 is provided with integraloppositely arranged flaps 5; As shown each of the flaps5 is of-va sizeabout equal to half the size of the bottom of the central portion 1 andits flange 4. The explosive tablet 3 is placed in the cavity 2 andsurrounded by suitable waterproof cement 6.

A disk 7 is placed over the tablet and is of a size to fit andcorrespond with the size and shape of the central portion2 and its 7flange 4:, and it is cemented thereto;

The flaps 5 are provided with strap receiving openings 8 and when theflaps are in a partiallyinwardly folded position a railengaging strap 9is threaded through these openings and the flaps are then completelyfolded: and cemented to thedisk 7. A second disk 10 is provided withstrap receiving openings 11, and'the ends of the strap are turnedoutward at right angles to the tor pedo and in parallel positions, andthe said second disk 10 is'placed in position on the folded flaps withthe strap 9 threaded through the openings 11 and the disk cemented inthis position;

the flaps 5 are heldby the strap 9, and the strap 9 is held by the flapsand by the disk 7 10, theparts when united serving to make a substantialand efficient construction, the. pull of the strap being substantiallyparallel to the bottom of the torpedo when applied to the rail; as shownin Fig. 2 the pull Vwill not serve to separate the flaps or the disk.
